Definitions

  • the invention relates to the field of pressure sensors.
  • a pressure force exerted on the surface of such sensors can be detected and makes it possible to generate a control signal for an ancillary organ.
  • the invention relates more particularly to pressure sensors integrating detection systems making it possible to generate an electrical signal representative of a variation in light intensity.
  • detection systems capable of generating an electrical signal representative of a variation in light intensity include a photosensitive element capable of transforming solar energy into electrical energy.
  • Certain detection systems can in particular integrate optical fibers each positioned in a cavity adjusted to the dimensions of the optical fiber. Deformations of the optical fiber cause a variation in the transmitted light intensity. In this case it is possible to equip one of the ends of the optical fiber with a light source and the other end of the optical fiber with a photosensitive element. Such a type of device then forms a pressure sensor as described in particular in the document FR-2 672 681 .
  • this type of sensor is complex to manufacture and requires manually positioning the different fibers inside cavities.
  • such a device is not suitable for generating a large number of distinct capture zones, as well as large zones and in particular greater than one square meter.
  • an objective of the invention is to facilitate the manufacture of capture systems, sensors, in particular pressure sensors, comprising optical fibers and capable of generating an electrical signal representative of a variation in light intensity.
  • the present invention relates to a pressure sensor whose main and subsidiary characteristics are defined by the appended claims.

  • the optical fibers can be arranged substantially parallel to each other and have cohesion facilitating their handling as well as their installation in an annex device in which the detection system can be positioned.
  • optical fibers contain alterations which may consist of a roughening of the exterior surface of each of the fibers. These alterations can also be formed by incisions allowing the transmission inside the optical fibers of a natural or artificial light ray incident at the peripheral surface of the optical fibers. It is also possible that the alterations are generated by thermal or chemical treatment applied to optical fibers.
  • optical fibers are then grouped in at least one beam at an edge of the textile element so as, for example, to bring the ends of the optical fibers into contact with a photosensitive element, such as for example a photodiode.
  • a photosensitive element such as for example a photodiode.

  • all or part of the optical fibers of the textile element can be covered with a coating layer of material having adaptive optical properties, in particular depending on the ambient environment. For example, it is possible to choose materials with the ability to change color (color, opacity, transparency, etc.) under the effect of a stimulus (light, temperature, pressure, humidity level, etc.). Thus, it is for example possible to produce devices for detecting a variation in the ambient environment, such as for example a meteorological variation.
  • the textile element may comprise a second group of optical fibers comprising on their peripheral surface alterations making it possible to laterally emit light at the level of at least one emission zone arranged in the immediate vicinity of the capture zone of the first group of fibers.

  • the detection system can also be coupled to an external light source.
  • the textile element comprises two groups of optical fibers, one making it possible to emit light laterally and the other making it possible to capture the emitted light.
  • One of the possible applications of such a detection system can be presence detection.
  • the light is reflected on the object then captured by the first group of optical fibers. This reflection of light therefore generates a variation in light intensity captured by the first group of optical fibers.
  • the light source can use a type of light ray having a predetermined wavelength and therefore, it can not be influenced by external radiation such as solar radiation or generated by lighting means d 'one piece in particular.
  • LiFi Anglo-Saxon acronym for "Light Fidelity”
  • the principle of LiFi is based on the coding and sending of data via amplitude or frequency modulation of light sources according to a well-defined and standardized protocol.

  • a person or an object exerts an effort on the surface of the pressure sensor, it brings the two textile elements closer to each other and thus improves the transmission of light. This then causes an increase in the light intensity captured by the photosensitive element arranged at the end of the optical fibers of the first group.
  • the level of transparency or opacity of the permeable layer can in particular be modulated according to the detection precision that we wish to give to the system.

  • the light-permeable layer can be obtained in different ways and in particular be constituted by an additional material positioned between the two textile elements or by an element of one of the textile elements, namely threads or a layer of 'coating.
  • the light-permeable layer can be formed by a sheet of foam.
  • the foam sheet constitutes an independent element attached between the two textile layers or even a coating layer of one of the two textile elements.
  • the light-permeable layer can be formed by binding threads belonging to at least one of the two textile elements.
  • These binding wires can for example have a diameter greater than that of the optical fibers of the first and/or the other group.

  • the light source can emit in the visible spectrum or not, for example infrared type light rays, so that the light radiation from the sun as well as that of interior lighting does not influence on the variation in light intensity detected by the photosensitive element.

  • all or part of the binding threads may be elastic.
  • the optical fibers can also be covered with a coating layer of material having adaptive optical properties.
  • the arrangement of all the optical fibers will depend on the application chosen.
  • a large number of configurations are possible, such as for example a matrix arrangement of emission and/or capture zones, or even following a particular pattern.
  • the textile element comprising the fibers can be presented in different forms, for example in the form of a textile sheet, or any textile element obtained for example by a process of weaving, knitting, embroidery, braiding, etc., and optionally shaped to form a 3D structure.

  • the optical fibers 3 belong to a first group and emerge from the textile sheet 2 at an edge 6 to be grouped in the form of a bundle 5 .
  • One end 9 of the beam 5 is then positioned facing a photosensitive element 8 making it possible to convert the radiation captured by the optical fibers into electrical energy.

These zones are defined using the different bundles 5 , 15 , 25 of optical fibers and can, therefore, be arranged parallel over the entire surface of the textile sheet 2 .
  • the different beams emerge from the textile sheet at an edge 6 and are placed opposite several photosensitive elements 8 , 18 , 28 themselves connected to a control unit.
  • the optical fibers 3 can be arranged both in a weft and/or in a warp inside the textile sheet 2 which is, in this particular case, a fabric.

  • Such a detection system therefore makes it possible to produce a reflective object sensor 26 . Indeed, certain objects may not reflect the light emitted by the optical fibers 23 and are therefore not identifiable by the detection system.
  • the detection system 20 can also have optical fibers presenting alterations at their periphery to emit visible light at the level of the textile sheet 22 .
  • This light emission zone 144 is also arranged in the immediate vicinity of the capture zone 4 and makes it possible to inform a user that the capture of variation in light intensity at the level of the textile sheet 22 has been carried out by the photosensitive element 8 and processed by the control unit.
